Introduction to the X11R7.7 Release
This release is the eighth modular release of the X Window System™. The next
full release will be X11R7.8 and is expected in 2013.
Unlike X11R1 through X11R6.9, X11R7.x releases are not built from one
monolithic source tree, but many individual modules. These modules are
distributed as individual source code releases, and each one is released when
it is ready, instead of only when the overall window system is ready for
release. The X11R7.x releases are made by “rolling up” the individual module
releases into a collection that is often affectionately called the “katamari”
by the developers.
The X11R7.7 release does not include all of the software formerly included in
the previous X Window System releases. It is designed to be a reasonable
baseline from which to start when building the window system for the first time
for a new installation, distribution, or package set. It does not provide a
full desktop environment, expecting a more feature rich set of applications to
be installed from one of the several excellent desktop environments available
for the X Window System. The X.Org developers continue to maintain and produce
new releases of much of the software that was formerly in the main window
system releases but is no longer included in the katamari releases, including
many of the Athena Widgets desktop applications that were provided as samples
in previous window system versions.
Once their window system build is established, most builders watch for
announcements of individual module updates on the xorg-announce mailing list
and update to those as needed. The X.Org Foundation currently releases the X
Window System katamari releases approximately once a year, but many modules,
especially the X servers and drivers, are updated more frequently between those
releases.
For help with how to build and develop in the modular tree see the Modular
Developer's Guide in the X.Org wiki.
We encourage you to report bugs using freedesktop.org's bug tracking system
using the xorg product, and to submit bug fixes and enhancements to <
xorg-devel@lists.x.org>. More details on patch submission and review process
are available on the SubmittingPatches page of the X.Org wiki.
The release numbering is based on the original MIT X numbering system. X11
refers to the version of the network protocol that the X Window system is based
on: Version 11 was first released in 1988 and has been stable for nearly 25
years, with only upward compatible additions to the core X protocol, a record
of stability envied in computing. Formal releases of X started with X version 9
from MIT; the first commercial X products were based on X version 10. The MIT X
Consortium and its successors, the X Consortium, the Open Group X Project Team,
and the X.Org Group released versions X11R3 through X11R6.6. Since the founding
of the X.Org Foundation in early 2004, many further releases have been issued,
from X11R6.7 to the current 7.7.
The next section describes what is new in the latest full release (7.7)
compared with the previous full release (7.6).
Summary of new features in X11R7.7
This is a sampling of the new features in X11R7.7. A more complete list of
changes can be found in the ChangeLog files that are part of the source of each
X module.
● Multi-touch events are now supported for touchpads and touchscreens which
can report position information on more than one finger providing input at
the same time, such as found on many tablets and recent laptops. These are
exposed by Xorg server 1.12 and later via the Xinput extension version 2.2.
● Additional Xinput extension features were introduced in version 2.1, as
supported in Xorg server 1.11, including allowing clients to track raw
events from input devices, additional detail in scrolling events so that
clients may perform smoother scrolling, and additional constants in the
Xlib-based libXi API.
● More progress has been made on the X.Org Documentation modernization - the
rest of the library and protocol specifications have been converted to
DocBook XML from the variety of formats they were previously in, and
support for cross-linking between documents hase been added. On most
systems these documents will be installed under /usr/share/doc/. They are
also posted on the X.Org website at http://www.x.org/releases/X11R7.7/.
● Fence objects are now available in Version 3.1 of the Synchronization
(“Sync”) extension. These allow clients to create a object that is either
in “triggered” or “not-triggered” state, and to perform actions when the
object becomes triggered. When a client requests a fence be triggered, the
X server will first complete all rendering from previous requests that
affects resources owned by the fence's screen before changing the state, so
that clients may synchronize with such rendering. Support for these has
been added to both the libxcb-sync and libXext API's.
● Pointer barriers were added by X Fixes extension Version 5.0. Compositing
managers and desktop environments may have UI elements in particular screen
locations such that for a single-headed display they correspond to easy
targets, for example, the top left corner. For a multi-headed environment
these corners should still be semi-impermeable. Pointer barriers allow the
application to define additional constraint on cursor motion so that these
areas behave as expected even in the face of multiple displays.
● The XCB libraries have begun adding support for the GLX and XKB extensions.
This work is not yet complete in this release, and not all of the
functionality available through these extensions is accessibile via the XCB
APIs. Some of this effort was funded by past Google Summer of Code
projects.
● Video and input driver enhancements. Please see the ChangeLog files for
individual drivers; there are far too many updates to list here.
● ... and the usual assortment of correctness and crash fixes.
Overview of X11R7.7
On most platforms, X11R7.7 has a single hardware-driving X server binary called
Xorg. This binary can dynamically load the video drivers, input drivers, and
other modules that are needed. Xorg has currently has support for Linux,
Solaris, and some BSD OSs on Alpha, PowerPC, IA-64, AMD64, Intel x86, Sparc,
and MIPS platforms.
Additional specialized X server binaries may be found depending on the platform
and build configuration, including:
Xdmx
is a proxy X server that uses one or more other X servers as its display
devices. It provides multi-head X functionality for displays that might be
located on different machines.
Xnest
is a nested X server, that operates as both an X client and X server. Xnest
is a client of the real server which manages windows and graphics requests
on its behalf. Xnest is a server to its own clients, and manages windows
and graphics requests on their behalf. To these clients, it appears to be a
conventional server.
Xephyr
is a X server that outputs to a window on a pre-existing “host” X display.
Unlike Xnest which is an X proxy, and thus limited to the capabilities of
the host X server, Xephyr is a full X server which uses the host X server
window as a “framebuffer” via fast SHM XImages.
Xvfb
is a virtual framebuffer X server that can run on machines with no display
hardware and no physical input devices. It emulates a dumb framebuffer
using virtual memory.
Xquartz
is an X server that interacts with the MacOS X native Aqua window system,
displaying windows on the Mac desktop and accepting input from the Mac
system devices, allowing X11 applications to be used in a native Mac
desktop session.
Xwin
is an X server that runs under the Cygwin environment, interacting with the
Microsoft Windows native window system, displaying windows on the Windows
desktop and accepting input from the Windows system devices, allowing X11
applications to be used in a native Windows desktop session.

Drivers marked with (*) are available for Linux only.
Xorg server
Loader and Modules
The Xorg server relies on the operating system's native module loader support
for handling program modules. The X server makes use of modules for video
drivers, X server extensions, input device drivers, framebuffer layers, and
internal components used by some drivers (like XAA & EXA).
The module interfaces (both API and ABI) used in this release are subject to
change without notice. While we will attempt to provide backward compatibility
for the module interfaces in stable releases, we cannot guarantee this.
Compatibility in the other direction is explicitly not guaranteed because new
modules may rely on interfaces added in new releases, nor is compatibility
across stable release branches (such as between Xorg 1.11 and 1.12).
Note about module security
The Xorg server runs with root privileges, so the Xorg server loadable modules
also run with these privileges. For this reason we recommend that all users be
careful to only use loadable modules from reliable sources, otherwise the
introduction of malware and contaminated code can occur and wreak havoc on your
system.
Configuration File
The Xorg server uses a configuration file as the primary mechanism for
providing configuration and run-time parameters. The configuration file format
is described in detail in the xorg.conf(5) manual page.
Note that this release features significant improvements for running the server
without a configuration file, so many users may find that that they don't need
a configuration file, or may rely on just snippets of configuration placed in
the xorg.conf.d directory.
If you do need to customize the configuration file, see the xorg.conf manual
page . You can also check the driver-specific manual pages and the related
documentation (found at driver tables) also.
The recommended method for generating a configuration file is to use the Xorg
server itself. Run as root:
Xorg -configure
and follow the instructions.
Command Line Options
Command line options can be used to override some default parameters and
parameters provided in the configuration file. Command line options available
for use with all X servers in this release are described in the Xserver(1)
manual page. Command line options specific to the Xorg server are described in
the Xorg(1) manual page.
Multi-head
Some multi-head configurations are supported in X11R7.7. Support for multiple
PCI/AGP cards may require a kernel with changes to support VGA arbitration.
One of the main problems is with drivers not sufficiently initializing cards
that were not initialized at boot time. This has been improved somewhat with
the INT10 support that is used by most drivers (which allows secondary card to
be "soft-booted", but in some cases there are other issues that still need to
be resolved. Some combinations can be made to work better by changing which
card is the primary card (either by using a different PCI slot, or by changing
the system BIOS's preference for the primary card).
Xinerama
Xinerama is an X server extension that allows multiple physical screens
connected to multiple video devices to behave as a single screen. With
traditional multi-head in X11, windows cannot span or cross physical screens.
Xinerama removes this limitation. Xinerama does, however, require that the
physical screens all have the same root depth, so it isn't possible, for
example, to use an 8-bit screen together with a 16-bit screen in Xinerama mode.
Xinerama is not enabled by default, and can be enabled with the +xinerama
command line option for the X server. Note that enabling Xinerama may disable
certain other extensions which are not compatible with Xinerama.
DDC
The VESA® Display Data Channel (DDC™) standard allows the monitor to tell the
video card (or in some cases the computer directly) about itself; particularly
the supported screen resolutions and refresh rates.
Partial or complete DDC support is available in most of the video drivers. DDC
is enabled by default, but can be disabled with a "Device" section entry:
Option "NoDDC". We have support for DDC versions 1 and 2; these can be disabled
independently with Option "NoDDC1" and Option "NoDDC2".
At startup the server prints out DDC information from the display, and can use
this information to set the default monitor parameters, or to warn about
monitor sync limits if those provided in the configuration file don't match
those that are detected.
Changed behavior in handling information from DDC
The X server previously used DDC information to detect screen size and pitch,
and compute DPI automatically, allowing fonts and other UI elements to
automatically scale to appropriate sizes. This mechanism worked reasonably well
for many single-monitor cases, but did not compute accurate DPI values for
multi-monitor cases or less common single-display setups. Thus, this
autodetection has been removed, and the X server no longer tries to compute an
appropriate DPI value. All users wanting fonts, physical measurement units, and
other UI elements scaled appropriately for their display (including users for
whom autodetection previously worked) must now set DPI or some other scaling
factor explicitly, either via the X server's -dpi option, a DPI setting in
their graphical enironment, or an alternate scaling mechanism provided by their
environment.
GLX and the Direct Rendering Infrastructure (DRI)
Direct rendered OpenGL® support is provided for several hardware platforms by
the Direct Rendering Infrastructure (DRI). Further information about DRI can be
found at the DRI Project's web site. The 3D core rendering component is
provided by Mesa.
Of note is that this release supports building the X server using the
system-wide libdrm. Previously, drm was kept in the server's tree and loaded as
a module, rather than using the standard OS mechanisms for managing shared
libraries of code. This requires that the server be built using a version of
libdrm of 2.3.0 or newer if it is to use DRM.
Terminate Server keystroke
The Xorg server has previously allowed users to exit the server by pressing the
keys Control + Alt + Backspace. While this function is still enabled by default
in this release, the keymap data usually used with Xorg, from the
xkeyboard-config project, has been modified to not map that sequence by
default, in order to reduce the chance that inexperienced users will
accidentally destroy their work.
Users who wish to have this functionality available by default may enable it
via the XKB configuration option “terminate:ctrl_alt_bksp”. For instance, the
setxkbmap command can be used to enable this by running:
setxkbmap -option "terminate:ctrl_alt_bksp"
The XKB Configuration Guide also includes an example xorg.conf.d file that sets
the “terminate:ctrl_alt_bksp” option by default on all keyboards. Many desktop
environments include XKB configuration options in their preferences to enable
this as well.
Grab debugging keystrokes
The Xorg server in this release provides various functions that can be mapped
to keystrokes to aid in the debugging of programs with errant input grabs.
The keysyms XF86LogGrabInfo and XF86LogWindowTree are defined to print
information to the Xorg log file on the current set of input grabs, and the
window tree of the current display. By default, these are available for use,
but not mapped to any key.
The keysym XF86Ungrab forces the X server to release all active grabs, which
may leave the clients holding them in an inconsistent state. XF86ClearGrab goes
further, killing the client connection of any client holding an active grab
when it is pressed. These keystrokes are intended to allow developers to debug
clients which are not properly releasing grabs or have problems occur while
input is grabbed. Since grabs are a fundamental part of the X client security
model, these keystrokes come with risks, such as the ability to bypass or kill
screen locks without knowing the password, and thus are not available by
default.
Users who are willing to accept the security risk and wish to enable this
functionality may do so via the XKB configuration option “grab:break_actions”.
Security issue in older xkeyboard-config releases
The xkeyboard-config data files included in this release have the grab
disabling keys correctly disabled by default, but versions before
xkeyboard-config 2.5 had them enabled, leading to the security risk described
above. When upgrading to the X server in this release be sure to also ensure
xkeyboard-config is a safe version. More details about this issue may be found
in advisories for CVE-2012-0064.
X Server startup state
The X servers in the X11R7.7 release now start by default with an empty black
screen and do not draw the mouse cursor until a client sets the cursor image.
To restore the classic behavior of starting with the grey weave pattern and ×
cursor, start the X server with the -retro option.
Font support
Details about the font support in X11R7.7 can be found in the “Fonts in X11R7.7
” document.
Default font installation directory
Previous versions of X installed font files under the lib/X11/fonts
subdirectory of the X installation directory (for instance, in X11R6 releases,
/usr/X11R6/lib/X11/fonts was commonly used). This release uses the default
installation path of the fonts subdirectory of the datadir setting from the GNU
autoconf configuration. For instance, if the fonts are configured with ./
configure --prefix=/usr, they will be installed under subdirectories of /usr/
share/fonts/X11. The font module configure scripts all take an option of
--with-fontrootdir=PATH to override the default. If --with-fontrootdir is not
specified, the fontutil pkg-config file will be consulted to find the
fontrootdir specified when the fontutil module was installed.
Bitmap font compression methods
The X11R7.7 release supports PCF format bitmap fonts stored uncompressed or
compressed via the compress, gzip, or bzip2 programs. To utilize bzip2
compression, the libXfont and mkfontscale modules must be built with the
--with-bzip2 — all other methods are enabled by default.
To specify which compression method to use when installing a font module from
X11R7.7 the configure scripts accept an option of --with-compression=TYPE,
where TYPE may be none, compress, gzip, or bzip2.
Type1 Font support
Previous versions of X came with two Postscript Type1 font backends. The
functionality from the “Type1” backend has been replaced by the Type1 support
in the “FreeType” backend.
CID Font support
The CID-keyed font format was designed by Adobe Systems for fonts with large
character sets. The CID-keyed format is obsolete, as it has been superseded by
other formats such as OpenType/CFF and support for CID-keyed fonts has been
removed from X11.
Build changes and issues
Strict compilation flags
Most of the modules in this release use stricter compiler flags when building
with the GNU gcc, LLVM clang, Oracle Solaris Studio, or Intel compilers. These
flags both enable more warnings, and promote some warnings to fatal errors in
the build. If these flags cause your build to fail, you can disable the flags
that turn these selected warnings into errors by adding
--disable-selective-werror to the configure command for the affected module. If
that is necessary for any X.Org modules, please report a bug in the xorg
product on https://bugs.freedesktop.org/.
Builders seeking even stricter compiler checks can instead pass
--enable-strict-compilation to the configure command to make all warnings
become errors.
Silent build rules
Most of the modules in this release use the AM_SILENT_RULES option of GNU
automake 1.11. When building the software, most output will show an abbreviated
format for the commands being run, such as:
CC xmen.o
To enable verbose output, showing all the arguments to the commands being run,
add the flag V=1 to the make command line or add the flag
--disable-silent-rules to the configure command.
New configure options for font modules
The bitmap font modules now accept a configure option of
--disable-all-encodings to set the default for all encodings to off, requiring
builders to then pass --enable- flags for each encoding to be built.
New configure options for documentation in modules
As many more modules now contain documentation to be converted from DocBook XML
to text, HTML, PostScript, and/or PDF formats, new standard options have been
added to the configure macros to control the build of these in the modules.
Enables or disables use of the xmlto command to translate
--with-xmlto=yes|no DocBook XML to other formats. All DocBook XML conversions
require use of this command.
--with-fop=yes|no Enables or disables use of the Apache fop command to
translate DocBook XML to PostScript and PDF formats.
--enable-docs=yes| Enables or disables the build and installation of all
no documentation except traditional man pages or those covered
by the --enable-devel-docs and --enable-specs options.
--enable-devel-docs Enables or disables the build and installation of
=yes|no documentation for developers of the X.Org software modules.
--enable-specs=yes| Enables or disables the build and installation of the
no formal specification documents for protocols and APIs.
Miscellaneous
This section describes other items of note for the X11R7.7 release.
Socket directory ownership and permissions
The socket directories created in /tmp are now required to be owned by root and
have their sticky-bit set. If the permissions are not set correctly, the
component using this directory will print an error message and fail to start.
Common socket directories that are known to be affected include:
/tmp/.font-unix
/tmp/.ICE-unix
/tmp/.X11-unix
These directories are used by the font server (xfs), applications using the
Inter-Client Exchange protocol (ICE) and the X server, respectively.
There are several solutions to the problem of when to create these directories.
They could be created at install time by the system's installer if the /tmp dir
is persistent. They could be created at boot time by the system's boot scripts
(e.g., the init.d scripts). Or, they could be created by PAM modules at service
startup or user login time.
The solution chosen is platform dependent, and the system administrator should
be able to handle creating those directories on any systems that do not have
the correct ownership or permissions.
Deprecated components and removal plans
This section lists current plans for removal of obsolete or deprecated
components in the X.Org releases. As our releases are open source, users who
continue to require these can find the source in previous releases and continue
to use these, but the X.Org Foundation and its volunteers have decided the
burden of continued maintenance and distribution in the core X11 releases
outweighs the benefits of doing so. In some cases, this is simply because no
one has volunteered to do continued maintenance, so if software is listed here
that you need, you can contact to volunteer to take
over maintainership, either inside or outside of the Xorg release process.
Future Removals
DGA 2.0 is included in 7.7. Documentation for the client libraries
can be found in the XDGA(3) man page. DGA should be considered
DGA deprecated; if you are relying on it, please let us know what you
version 2 need it for so we can find better solutions. In this release, support
has been removed for all DGA rendering and mapping code, leaving just
mode setting and raw input device access.
Xorg server 1.4 started using the HAL framework to discover connected
input devices, receive notification of hotplug events for them, and
Input to retrieve configuration parameters for them. The HAL maintainers
device have since deprecated HAL, so the X.Org developers have begun
discovery replacement with alternatives. As a result, configuration of input
via HAL devices via HAL *.fdi files is no longer supported on Linux platforms
using udev, and may not be supported on other platforms in future
Xorg server releases.
As described in the section called “Overview of X11R7.7”, this
Nested release contains several X servers that either display onto another X
and server (Xephyr & Xnest), or render into a virtual memory framebuffer
virtual X (Xvfb & Xfake). These may be replaced in a future release by use of
servers the Xorg server with the xf86-video-nested and xf86-video-dummy
drivers which perform the same tasks.
Removed in this Release
This release no longer contains the following drivers, due to lack
of maintainers with relevant hardware. Existing driver versions
may work with current Xorg servers, but they are not being
actively updated to support Xorg driver API & ABI changes.
